TRANSOM FOR CAR TRUCKS.

SPECIFICATION forming part of Letters Patent N 0. 604,610, dated May 24,1898.

7 Application filed January 10, 1898. Serial No. 666,174. (No model.)

T at whom it may concern.-

Be it known that LTHoMAs M. GALLAGHER,

a citizen of the United States, residing at the city of St. Louis, inthe State of Missouri, have invented a certain new and usefulImprovement in Transoms for Oar-Trucks, of which the followingis a full,clear,and eXact description, reference being had to the accompanyingdrawings, forming part of this specification.

My invention relates to an improved form of transom for that class ofcar-trucks having arch-bar side frames, a common example of which is tobe found in what is known as the diamond-frame truck.

The object of my invention is to construct such a transom in amanner'that will enable it to be readily attached to the side frames andwhich will be of such a construction as to receive the bolster andbolster-springs, while requiring but little labor in putting the partstogether. I

My object, further, is to make such a transom in a manner that no partsof it may be lost or become loosened or displaced, and to this end 1form the transom consisting of a body open at the top to receive thebolster and having at each end a seat to receive the bolster-sprin gs,and, further, being formed at each end so as to receive the arch-bars ofa truck-frame and be connected thereto, all of the parts being form edin one integral casting.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims. I

Figure I is a side View of a car-truck provided with my improvedtransom, part of the transom being shown in section, taken on line I I,Fig. II. Fig. II is a sectional view taken on line II II, Fig. I, withpart of one side of the transom broken away and with one end of thetransom shown in section. Fig. III is a view corresponding to Fig. II,but showing a form of seat adapted to receive an elliptic spring insteadof a coil-spring.

1 represents the side frames of a car-truck, of which 2 and 3 are thearch-bars. This is a common form of truck-frame and is generally knownas a diamond frame.

4 represents a bolster, and 5 the transom to which my invention relates.The transom is composed of side pieces 6 and '7, which are preferablystrengthened by horizontal ribs or flanges 8 and vertical ribs orflanges 9. The transom is open at the top to receive the bolster 4, andthe central part of the bottom of the transom is left open. Near eachend of the transom, at the bottom, is a shelf or seat 10, upon whichrest the bolster-springs 11, which may be in the form of coil-springs,as shown in Figs. I and II, or in the form of elliptic springs, as shownin Fig. III. Each end of the transom is formed to receive the arch-bars2 and 3 of the truck-frame. My preferred way of forming the ends of thetransom to receive these arch-bars is to provide each end with an uppergroove 12 to receive the arch-bar 3 and a lower groove 13 to receive thearch-bar 2. The ends of the transom that receive the arch-bars and thespring seats referred to are formed integral with the sides 6 and 7 ofthe transom, the whole being made in a single casting, preferably ofsteel.

At each end of the transom are lugs 14', perforated to receive the bolts15, by which the arch-bars are tied to the transom, as shown in Fig. I.These lugs or cars 14 constitute an integral part of the transom, and itwill thus be seen that the transom as a whole consists of a single piecemade by the cheap method of producing a transom-by casting 8o ittl1at itcan readily be combined with and attached to the side members of atruck-frame, and that there are no parts associated with it which areliable to become loose or misplaced.

I claim as my invention- 1. As a new article of manufacture, a transomfor car-trucks composed of sides having ends formed to receive thearch-bars of a truck-frame, and spring-seats located at the 0 bottom ofthe sides near the ends all made in one integral casting, substantiallyas set forth.

2. As a new article of manufacture, a transom for car-trucks composed ofsides having ends provided with grooves to receive the arch-bars of atruck-frame, and spring-seats located at the bottom of the sides nearthe ends all made in one integral casting, subcated at the bottom of thesides near the ends,
